This probably introduced more problems, because irq code has to be fast? During recording through USB2 this code made the system not crash but it wasn't able to answer any request (SSH, HTTP, login from serial console ...) Is this info useful? I attached only one of the kernel panic logs. If you would like to see the others, please tell me. I am not sure if the dvb.log tells something of worth at all. Jan
